Action Pump 600 GPH Manual Lift Pump -

The action pump 600 GPH was exactly what I needed to build a closed water system for preschool students. While there is some leakage where the diaphragm is attached to the pumping handle the pump has stood up under the ordeals which only 3 through 5 year olds can put it. It took a little time to stop the bolts from unscrewing, but the problem was easily handled with some lock-tite designed to allow you to "break" the weld to replace the diaphragm should that fail. Five weeks of pumping from 8 to 3 and still going strong. Definitely a 5 star.

One of the ends snapped when i was pumping, can't find a replacement part anywhere online for it (snapped after the bolted one way valve) pump seems to do its job with minimal leaking but can't have any odd pressures on it or it was already weakened or cracked before I had used it

As needed

Haven’t had to use it yet but had one just like it and it works great

pretty sure it broke after the first use and never really got the juices flowing
